AMD OE23VSWHP4DGIE Quad-Core Socket F Server Processor

The AMD OE23VSWHP4DGIE is an Opteron 23VS quad-core processor built on AMD's 45nm Shanghai core for Socket F (LGA1207) server and workstation platforms. Running at a fixed 2.8GHz with a 115W TDP, this chip targets legacy dual- and quad-socket server refreshes and replacement-part builds where matching an existing Socket F platform matters more than chasing the newest silicon. For integrators maintaining older rack infrastructure, sourcing a factory-new OE23VSWHP4DGIE to replace a failed or end-of-life unit keeps a working platform in service without a full board swap.

Overview

Part of AMD's K10 Opteron Gen 3 family, the 23VS sits in the Shanghai generation that succeeded the original Barcelona-core Opterons, bringing a die shrink to 45nm and a larger L3 cache alongside a refined DDR2 memory controller. It's a four-core, four-thread part with no simultaneous multithreading, which matches the era's server workloads that scaled on core count rather than thread count. Socket F compatibility means this part drops into existing dual-socket AMD server boards without a platform redesign — the primary reason to buy this specific model rather than a newer, incompatible Opteron generation.

Key Features

• 2.8GHz Frequency at 14x Multiplier: A fixed 2000MHz bus feeding a 14x multiplier lands you at 2.8GHz per core across all four cores — predictable, unthrottled clock behavior for workloads that need consistent per-core performance rather than burst turbo.
• 4 Cores / 4 Threads: Four physical cores with no hyperthreading gives you dedicated execution resources per thread — useful when running virtualization or multi-process workloads where you want to avoid the scheduling contention that comes with SMT-shared cores.
• 6MB Shared L3 Cache: A 6MB L3 shared across all four cores reduces main-memory round trips on multi-threaded workloads, meaningfully cutting latency versus earlier Opteron generations that shipped without L3 at all.
• 2MB Shared L2 Cache: Backing the L3, a 2MB shared L2 keeps frequently-accessed data closer to the cores, smoothing out performance on mixed workloads that jump between processes.
• 64KB L1 Code + 64KB L1 Data: Split instruction and data L1 caches keep the fastest cache tier close to each core's execution pipeline — standard practice for minimizing pipeline stalls on cache misses.
• 45nm Process Node (Shanghai Core): The Shanghai die shrink from 65nm to 45nm improved power efficiency and let AMD grow the L3 cache versus the prior-generation Barcelona Opterons — this is the generation to target if you're standardizing a fleet on Socket F K10 parts.
• 115W TDP: A 115W thermal envelope means your existing Socket F server cooling — designed for this Opteron generation — will handle this chip without a heatsink or airflow redesign, simplifying drop-in replacement.
• DDR2 Unbuffered Memory Controller: The on-die DDR2 unbuffered controller defines your memory compatibility ceiling — plan your DIMM sourcing around unbuffered DDR2 modules rated for this platform, not registered or DDR3 memory.
• Socket F (LGA1207) Package: Socket F is a land-grid-array package requiring a compatible Socket F motherboard — confirm your board revision before ordering, since Socket F spans several distinct Opteron generations with different chipset requirements.
• 1.325V Operating Voltage: A defined 1.325V spec lets you cross-check VRM compatibility on older server boards before installation, avoiding voltage-mismatch boot failures.

Integration & Compatibility

This part is a direct fit for Socket F (LGA1207) server boards built for AMD K10 Opteron Gen 3 processors — typically dual-socket 2000-series server platforms of that era. Because Socket F covers multiple Opteron generations with different memory and chipset requirements, verify your motherboard's supported CPU list before ordering the OE23VSWHP4DGIE as a replacement or upgrade part. This is genuine, factory-new AMD silicon sourced through commercial-grade B2B channels — not a grey-market or parallel-import part — which matters when you're stocking spares for production server infrastructure that can't tolerate a counterfeit or remarked chip. Pair it with unbuffered DDR2 memory rated for your board's Socket F platform to stay within the processor's supported memory ctrl. specification.

Frequently Asked Questions

Q: What socket does the AMD OE23VSWHP4DGIE use?

A: It uses Socket F (LGA1207), the AMD server socket used across several Opteron generations. Confirm your motherboard supports the K10 Opteron Gen 3 (Shanghai) family specifically before ordering.

Q: What is the clock speed and core count of the OE23VSWHP4DGIE?

A: It runs at 2.8GHz across 4 cores and 4 threads, using a 2000MHz bus speed and a 14x multiplier.

Q: What memory type does this processor support?

A: The OE23VSWHP4DGIE has an on-die DDR2 unbuffered memory controller, so it requires unbuffered DDR2 memory compatible with your Socket F motherboard.

Q: How much cache does the OE23VSWHP4DGIE have?

A: It has 64KB L1 code cache, 64KB L1 data cache, 2MB shared L2 cache, and 6MB shared L3 cache.

Q: What is the TDP and operating voltage?

A: The processor has a 115W TDP and runs at 1.325V.

Q: Is this a genuine, factory-new AMD processor?

A: Yes — this is factory-new AMD silicon sourced through commercial-grade channels, not a grey-market or parallel-import part.

The OE23VSWHP4DGIE is one I get asked about from teams still running dual-socket Socket F server chassis that they're not ready to forklift-upgrade. This is a Shanghai-core Opteron 23VS at 2.8GHz — 4 cores, 4 threads, 6MB of shared L3 — which puts it squarely in the K10 Gen 3 lineup rather than the earlier Barcelona parts that lacked L3 entirely.

Technical Highlights:

• 6MB Shared L3 + 2MB Shared L2: That two-tier shared cache structure is the real generational jump over Gen 2 Opterons — it cuts memory latency on multi-process server workloads noticeably versus parts with L2-only cache hierarchies.
• 115W TDP at 2.8GHz / 14x multiplier: A fixed 2000MHz bus times a 14x multiplier gets you the full 2.8GHz on all four cores simultaneously, inside a 115W envelope your existing Socket F cooling was already sized for.
• DDR2 Unbuffered Controller at 1.325V: The on-die memory controller locks you to unbuffered DDR2 — check this against your board's installed DIMMs before you order, since registered DDR2 or any DDR3 won't work with this controller.

Deployment Considerations:

• Socket F spans multiple Opteron generations with different chipset and memory requirements — verify your motherboard's supported-CPU list names the K10 Gen 3 Shanghai family specifically, not just "Socket F," before you buy this as a replacement part.
• No SMT means thread count equals core count (4/4) — plan your VM or process density around four real execution contexts, not eight.

This is the part to stock as a hot-spare or replacement for existing dual-socket Socket F Opteron server fleets running the K10 Gen 3 Shanghai generation — not a fit for anyone spec'ing a new server platform from scratch.
